AI Thread Summary
The discussion centers on understanding the weight of 2.9955623e+05 tonnes, which is equivalent to 299,556.23 tonnes or 299,000 tonnes when rounded. The term "tonne" refers to a metric ton, equal to 1,000 kilograms. Participants clarify that the scientific notation indicates a large mass and discuss the importance of using the correct density measurement for accurate calculations. The density input can significantly affect the results, depending on whether it is in kilograms per cubic meter or grams per cubic centimeter. Accurate density values are crucial for ensuring the correct mass calculations in engineering design.

Hi,

Im a studying designer currently working with an engineering CAD program. I have calcualted the mass of the part using an analysis feature in the program. However, I have very little engineering interlect and cannot completely understand the results.

The returned result is 2.9955623e+05 TONNE

If anyone can help me understand this it would be much appreciated.

Cheers

Daniel

Are you asking about the scientific notation or the unit? A 'tonne' usually means a metric ton, which is 1000 kilograms. The number is "computerese" (it goes back to FORTRAN notation) for the value expressed in scientific notation; here, this would be 2.9955623·10^5 or 299,556.23 (which is probably way more significant figures than the number is good for...).
 
1 tonne = 2204.6226 pounds

It's called a metric ton.

You got the 2.99 x 10^5 part of it I'm guessing.
 
I appreciate your immediate reply

I thought that may be the conversion but does that mean that it is 299,000 tonnes!? If so the density assigned to the part is incorrect so I must change it
 
What did you use for the density? Does the input want kilograms per cubic meter or grams per cubic centimeter? (That would make a difference of a factor of 1000.)
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
